ACTIVATING THE TA FLAG
The Travel Announcement feature is a temporary command. This flag must coincide with the
actual voice warning of a traffic condition. The encoder includes a means to access this flag with a
manual switch closure, which will doubtlessly prove as much faster, convenient and reliable than
software control of the TA function.
A run of twisted-pair cable may be taken from one of the GPIs, part of DB15 on the rear
of the encoder to a normally open momentary (spring-return!)
push-button switch located conveniently at the announcer’s operating position. In order for the
configuration to be successful, the GPI should be set to work as a TA flag switch.
The TA flag will be transmitted as long as the switch is held down. It is important that this alert is
active only for the duration of a traffic announcement. The TA flag must be turned off immediately
after completing the verbal traffic warning. Furthermore, the safety mechanism, known as “TA
Timeout”, may also be activated. This is possible happen when the time for which the TA flag is
exceeds the one set, and then TA flag RDS data will be disabled. Please note that the value set for
the TA will remain ON.
